Inter-Beam Phase Factor Tracking

5. The method of claim 1, wherein the inter-beam phase factor tracking reference signal configuration indicates that the BS is to aperiodically or semi-persistently transmit the inter-beam phase factor tracking reference signal.

29. The BS of claim 25, wherein the set of inter-beam phase factors is associated with reducing loss in array gain over an overlap region of the at least two static directions.

30. The BS of claim 29, wherein the set of inter-beam phase factors is associated with maximizing equivalent isotropically radiated power for uplink transmissions to the BS.
